Abstract: A beam steering control system includes a beam angle controller, a fast axis controller configured to receive a first command signal from the beam angle controller and configured to control a first axis component of a light pattern, and a slow axis controller arranged within a closed-loop system. The slow axis controller is configured to receive a second command signal from the beam angle controller and control a second axis component of the light pattern.

Abstract: A method includes detecting an object using a first light scan profile and, in response to detecting the object, using a second light scan profile with increased resolution in a region of interest relative to the first scan profile. The second light scan profile is based, at least in part, on a width of the region of interest, a number of scanlines for the region of interest, and an angular offset to the region of interest.
